Do not mangle project names on Asana

[langri-sha]

Relevant integration (if any):

https://app.asana.com

🐛 Describe the bug

Project names with trailing whitespace or certain characters escaped are getting mangled and we're not able to match the related project from the list of projects.

Expected behaviour

Project names aren't mangled and they can match existing, related projects.

Steps to reproduce

• create a project in Asana that has trailing whitespace
• start a TE in one of the related pages
• the project name isn't matched
